The Role of Music in Horror Films

Music is a fundamental element in horror films, contributing to the overall atmosphere and guiding the audience’s emotions. By using specific musical techniques and tools, music can heighten tension and evoke fear in viewers. This article explores how music is used in horror films to create terrifying and impactful effects.

Visual and Musical Impact in Horror Films

The famous scene in Alfred Hitchcock’s “Psycho” is a prominent example of the power of music in horror. The music composed by Bernard Herrmann for this scene added a new dimension of terror through the use of shrieking violins that mimic the victim’s screams. Hitchcock later confirmed that 33% of the film’s impact was due to the music.

Research shows that frightening music activates the brain’s alarm response system, increasing its effect on viewers. Sounds that mimic human screams, such as the rough sound produced by high air pressure through vocal cords, are considered some of the most unsettling musical elements.

Scary Musical Techniques

To produce frightening sounds musically, musicians must push the boundaries of their instruments. As with the violins in “Psycho,” musicians must push the strings to their limits to generate the harsh sound that instills fear in listeners.

In a 2020 study, researcher Caitlyn Trevor and her team discovered several musical cues that mimic screams in horror film music. These cues activate the amygdala, a part of the brain responsible for processing danger.

Types of Scary Music

There are two main types of scary music: anxiety-inducing and terrifying music. A study conducted in 2023 showed that terrifying music is usually loud and dense, while anxiety-inducing music is more varied and uses subtle audio cues to keep listeners on edge.

Some directors use low-frequency sounds to create an intangible sense of danger, as these sounds resemble thunder or earthquakes, triggering an instinctive response in humans.

Rhythm and Musical Expectations

Fast rhythms resembling heartbeats are used to evoke anxiety and tension. Repetitive and regular rhythms give the impression that something is approaching. In contrast, unexpected rhythms and deviations from the pattern are used to confuse listeners and induce anxiety.

Breaking expectations is considered one of the strongest musical techniques in horror films, as unexpected music can activate the amygdala and trigger viewers’ fears.

Conclusion

Music plays a crucial role in horror films through various techniques ranging from vocal mimicry of screams to manipulating viewers’ musical expectations. While some musical elements are naturally frightening, many rely on the cultural expectations of listeners. Understanding these dynamics can help enhance the viewing experience, making it more thrilling and terrifying.
